Yep, left side mount. That's not a problem right? I know that right sided mounts are more common and "correct" for the states, but I like the fit and function of the left side.

not a problem if you don't mind not being able to see around traffic without putting your sidecar into the opposing lane. If it is strictly an offroad rig it won't make any difference. If it will be on the street it is a bad idea unless there is a compelling functional reason to set it up that way. The only thing that comes to mind is rural mail delivery
